(0.3-3)×1600MM Coil Slitting Machine

KINGREAL (0.3-3)×1600MM Coil Slitting Machine used to slitting the metal sheet coil into specified widths and finally rewinding, which can process different materials including stainless steel, galvanized steel, cold rolled sheet and hot rolled sheet, and the applicable thickness range is 0.3-3MM, common coil width is 1600MM, KINGREAL supports customized design of metal slitting machine. KINGREAL can offer steel coil slitting machines with a variety of features and designs to meet the various manufacturing needs of its clients. Coil Slitting Machine can separated into thin plate coil slitting machines, medium plate coil slitting lines, and heavy gauge steel slitting machines based on material thickness; narrow strip slitting machines, double knife slitting head slitting machines, and 220/min high-speed slitting machines are divided based on production demand.

① Cantilever Decoiler

1. Function of Cantilever Decoiler: It carries steel coils, tightens and expands their inner diameter, uncoils and discharges them, or recycles them.
It is made up of a frame, spindle, expanding and contracting reel, unwinding and pressing device, auxiliary support, brake device, and power portion. It supports the coil plate and gives the steel strip tension.

2. Building
a) Main frame: composed of steel, A3 steel plate, and #45 steel forging bearing seat that is not deformed after welding and annealing;
b) Use a slider-type push-pull expansion reel form to raise and shrink the reel. It has four curved plates made of No. 45 steel, wire-cutting slider pairs, and an expansion diameter of ~<470mm–520mm (plus a rubber sleeve to reach ~\610mm). The reel's effective working length is 1650mm, and the overall mandrel makes sure that the reel up and down when the concentricity.

②High Speed Slitter Machine

Strip coils can be sliced longitudinally into different widths using a slitter machine. By varying the combined spacer, the sheared product's breadth can be freely adjusted. When adjusting the knife shaft, the upper shaft is adjusted like a worm gear while the lower shaft remains fixed. 

The distance between the upper and lower shafts can be precisely controlled by the synchronized adjustment of the knife shaft spacing mode. The upper and lower knife shafts are fitted with a protective sleeve for the knife at the shaft end, and they use nuts for axial fastening. The primary device uses a motorized seat frame that may be opened and closed (motor-driven), making blade replacement easy.

③Pre-separation, Tensioner, Guide roller

1. Structure and purpose: After slitting, separate the strips to make it easier to close and avoid stacking when going through the tensioner. Two sets of dividing disks are present. To facilitate replacement and cleaning, the separating disk's shaft can be easily removed from the operating side.

2. The purpose of the guide roller, which is a seamless steel tube with a PU rubber covering and a Τ450mm dynamic balancing treatment, is to guide the belt into the winder.

3. Pallet device: consisting of drive system and frame. The purpose of the hydraulic drive structure used in pallet device lifting is to move the board toward the winder.

Based on specific client requirements and actual production scenarios, KINGREAL custom-designs specialized performance features for each critical component of coil slitting machine. In particular, the customized designs for the main slitter and tension device have resulted in significant improvements in both production efficiency and product precision.

Dual Slitter Head Design for Coil Slitting Machines

The main slitter is responsible for precisely shearing wide-format sheet materials longitudinally—according to preset widths—to transform them into narrow strips that meet specific production requirements. The dual slitter head design enables the simultaneous execution of production operations and tool changes: while one slitter head is actively engaged in production, the other can undergo tool replacement and calibration offline in parallel. This eliminates the need to halt operations to wait for tool changes, effectively minimizing downtime and significantly boosting slitting efficiency, thereby catering perfectly to the demands of high-volume, continuous production environments.

Belt Tension Design for Coil Slitting Machines

The belt tension design is primarily utilized in coil slitting lines for materials such as steel strips and aluminum sheets, where strict standards regarding surface scratches are paramount. By employing symmetrically positioned upper and lower belts (or felt pads), the system gently but firmly secures the material being slit. It leverages the friction generated at the contact interface to provide uniform and stable tension for the steel strip during the recoiling process. The key to this design lies in ensuring that the belts move in perfect synchronization with the material; by eliminating any relative slippage throughout the entire process, it fundamentally prevents surface scratches on the material, thereby safeguarding the aesthetic quality of the finished product.
